How do I clean the ring around the pool tile?
Lower the Water LevelDrain a bit of the pool’s water so that the water level is below the ring on the tile. Do not completely drain the pool unless you are also changing the water at this time. It is easier to remove the stain without water in the pool.Clean With VinegarSoak a clean, soft cloth in vinegar. Press the rag to the ring for 10 minutes. Remove the rag, and scrub the tile with the rag or with another sponge, which should loosen the calcium buildup so that you can scrub it off.Use a Rust RemoverUse a product designed to remove hard water stains or rust, or purchase a product designed specifically to remove mineral buildups from pools. Apply the product to a soft, clean cloth or sponge, and scrub the ring until it lifts. Use it according to the instructions.
